Beetle-inspired Switch Uses Water For Bonding

Summary:
A new switch designed by Cornell University engineers uses water droplets to create very strong adhesive bonds that can flicked on and off in an instant. The switch was inspired by a mechanism found in palm beetles and is described in the Proceedings of the National Academy of Sciences (Vol. 102 (34) 11974-11979, 2005).

The droplet switch shown here toggles between a big droplet positioned above and below the plate using applied voltage. This novel electro-mechanical switch is capable of working by itself or in larger arrays, and has fast switching times with low voltages, no moving solid parts and can be made very small. Applications are envisioned in the areas of mechanics, micro-fluidics and optics, among others. (Vogel/Steen, copyright PNAS)

ITHACA, N.Y. -- Imagine this: A tiny, fast switch that uses water droplets to create adhesive bonds almost as strong as aluminum by borrowing a mechanism found in palm beetles.
